The ARIS Explorer 1800 delivers image clarity that is unmatched by any other sonar in its class. At 1.8 MHz, this imaging sonar provides the detail that is required for thorough inspection. At the lower frequency, 1.1 MHz, the ARIS’s clarity makes it an ideal tool for detecting targets up to 35 meters. These near-video-quality images are presented through powerful, multifunctional software. The ARIS 1800 is perfect for fisheries/marine biology because of its ability to deliver necessary detail in real-time. This level of resolution is deal for inspecting underwater structures, hulls and berth sweeps, and for military and law enforcement when accuracy is a must.
